Which of the following reduce heterozygosity?
A)migration
B)directional selection
C)large population size
D)balancing selection
E)mutation

Question

Quizplus · Accepted Answer

Directional selection favors one phenotype over another, causing a decrease in genetic diversity and reduced heterozygosity within the population. The other choices either do not necessarily reduce heterozygosity or may even increase it. Migration can increase the gene flow between populations and increase heterozygosity. Large population size can maintain or increase genetic diversity. Balancing selection can maintain heterozygosity by favoring multiple alleles. Mutation introduces new genetic variants and can increase diversity.
